Chloe Sevigny is concerned that her latest role might make her “unattractive” to men.

Sevigny stars in the British series “Hit & Miss,” coming soon on DirecTV, about an assassin with a secret — that she is a pre-op transsexual. For the part, which Sevigny calls her “most extreme,” she has to wear a prosthetic penis.

“I cried every day when they put it on,” Sevigny tells Culture magazine. “I felt very exposed… having people so close to your personal parts anyway — who you’re not sleeping with — for an hour-and-a-half each day, to put it on.”

But the experience got even more strange.

Sevigny continued, “Then looking in the mirror… it was weird. I was lonely and I felt really unattractive. I was confused about my desirability — was I desirable? — in having put that on, and having men see me with that on.”

Sevigny has not shied away from edgy parts in the past, starring in “Boys Don’t Cry” and HBO’s “Big Love.” But Sevigny says “Hit & Miss” took things to another level for her.

“I think it might be one of the most extreme roles I’ve done,” she said. “If people can believe what’s-her-name in ‘Avatar,’ hopefully they can believe me as a pre-op.”
